4854 Sound glitches every 30 seconds mschinca "I know there are other opened issues involving sound so some may be related to mine.
I run VirtualBox 3.0.4 on a Windows XP 32 bit host (Athlon 64 X2 1,9 ghz machine) and Windows XP 32 bit guest. When playing an mp3 file (or tv streaming) using Windows Media Player from the guest, at a very regural interval (30 seconds) the sound gets distorted (like a ""scratching"" effect) for a fraction of second and then gets smooth again. It's easy to predict the following audio ""glitch"". No other program running, in task manager cpu load looks very low both in host and in guest.
I also tried VLC media player on the same guest, same mp3 file and in this case audio playback is more unstable, when starting the playback the sound is garbled for some second, time goes faster then playback goes smooth. Also clicking on the gui menu causes the sound become garbled for 15-20 seconds, irregular playback speed with ""skipping"", then playback becomes again smooth. Audio glitches still present every about 30 seconds. Still low cpu usage." defect closed minor other VirtualBox 3.0.4 obsolete Windows Windows
